My comment:
(1) The first quotation is true?
(2) The second quotation is Taiwan's strategy, before it can purchase more
submarines which former US president George W. Bush promised in 2001.
(3) The report cites
Mackenzie Eaglen and Jon Rodeback, Submarine Arms Race in the Pacific: The
Chinese Challenge to U.S. Undersea Supremacy. Heritage Foundation, Feb. 2,
2010 (Backgrounder #2367).
http://www.heritage.org/Research/nationalsecurity/bg2367.cfm
In my view, the backgrounder does not say much.
(4) Virginia class submarine
http://en.wikipedia.org/wiki/Virginia_class_submarine
(The attack submarines "were designed as a less expensive alternative to the
Cold War era designed Seawolf-class attack submarines, and they are slated
to replace the aging Los Angeles class submarines, seventeen of which (from
a total of 62) have already been decommissioned.")
